Hello,
I have a Pioneer SX-1250 reciever from the 1970s which a local thrift
store had been about to trash. It looks great aside from a few
scratches and is pretty clean. However, the right channel is weak- it
comes in much quieter than the left. Also, the unit emits a quiet but
audible buzzing noise-not from the speakers, but from the unit itself.
Any idea what this might be? And would it be expensive to fix? I
understand these were first-class units in their day, and I would
consider repairing it if the cost were not too exorbitant
